Abstract
A solid densimeter comprises two connected electronic balances. The bases of the electronic balances are provided with two trays which are respectively placed with a liquid discharging barrel and a beaker. An opening of the liquid discharging pipe at the upper part of the liquid discharging barrel is provided above the beaker. The base is composed of a pushbutton combination frame and a display screen. The solid densimeter according to the invention has the advantages of simple structure, low cost and convenient operation. The solid densimeter not only can increase the speed for measuring the density of the solid body, but also can increase the precision for measuring the density of the solid body.
Description
(1) technical field
The invention belongs to the surveying instrument technical field, be specifically related to a kind of solid body densitometer.
(2) background technology
In the prior art, the method for traditional measurement ground density weighs out earlier the quality of the soil body in the balance, then the soil body is put into one and is prepared in advance and fills certain liquid, and outage is circumscribed with an empty graduated cylinder, measures soil body volume.The density of the soil body is exactly the volume of soil body quality divided by the soil body.In whole process, not only relate to numerical evaluation; And operate miss is bigger, because after the quality of measuring the soil body, the soil body is put into discharge opeing bucket process, might have a small amount of soil body and lose; Operation is also inconvenient still more.
(3) summary of the invention
Existing have complicated operation when measuring solid matter such as the soil body in order to solve, problem such as personal error is big, the invention provides a kind of simple to operate, and the very little solid matter density measuring instrument of personal error.
Solid body densitometer of the present invention, knob combo box, display screen are arranged on the support, be provided with first electronic balance and second electronic balance in the support, first electronic balance is provided with the discharge opeing bucket that is used to put into solid to be measured, second electronic balance is provided with beaker, the discharge opeing bucket is connected with discharging tube between the beaker, the liquid of density less than solid to be measured is housed in discharge opeing bucket and the beaker, the measured value of first electronic balance and second electronic balance all is transported to central processing unit, central processing unit descends column operations, and the result is outputed to display screen:
ρ＝ρ
1*m/m
1
Wherein: ρ
1It is the known fluid density of being adorned in discharge opeing bucket and the beaker
M is the relative mass sum of surveying on two balances, is exactly the quality of tested solid
m
1Be the measured value of second electronic balance, i.e. the quality of liquid that beaker increases
As preferred a kind of scheme: described knob combo box is made up of " ON/OFF " key, " zeroing " key, " fluid density " key, combination of numbers frame and pilot lamp.
The present invention couples together two electronic balances, is used for measuring the quality and the volume of the soil body, calculates the density of solid then with the counter of balance self, shows quality, volume and the density of the soil body on display screen.
Beneficial effect of the present invention mainly shows: structure is very simple, and cost is very low, and is easy to operate, and it both can improve the measuring speed of soil body density, also improves the measuring accuracy of soil body density.
(4) description of drawings
Accompanying drawing 1 is a structural representation of the present invention.
Accompanying drawing 2 is a knob combo box synoptic diagram of the present invention.
(5) embodiment
With reference to accompanying drawing: solid body densitometer of the present invention, knob combo box 4 is arranged on the support 3, display screen 5, be provided with first electronic balance 6 and second electronic balance 7 in the support, first electronic balance 6 is provided with the discharge opeing bucket 1 that is used to put into solid to be measured, second electronic balance 7 is provided with beaker 2, discharge opeing bucket 1 is connected with discharging tube 13 between the beaker 2, the liquid of density less than solid to be measured is housed in discharge opeing bucket 1 and the beaker 2, the measured value of first electronic balance 6 and second electronic balance 7 all is transported to central processing unit, central processing unit descends column operations, and the result is outputed to display screen:
ρ＝ρ
1*m/m
1
Wherein: ρ
1It is the known fluid density of being adorned in discharge opeing bucket and the beaker
M is the relative mass sum of surveying on two balances, is exactly the quality of tested solid
m
1Be the measured value of second electronic balance, i.e. the quality of liquid that beaker increases
Knob combo box 4 is made up of " ON/OFF " key 8, " zeroing " key 11, " fluid density " key 12, combination of numbers frame 9 and pilot lamp 10.
By behind " zeroing " 11 keys, suppose that the relative mass on two pallets is 0, after tested solid is put into discharge opeing bucket 1, the quality m that the relative mass sum is exactly tested solid that surveys on two balances, when liquid no longer when discharge opeing bucket 1 flows into beaker 2, the volume V1 of liquid that beaker 2 increases is the volume V of tested solid.Balance 7 can be measured the quality m1 of liquid that beaker 2 increases, and known fluid density ρ 1, can obtain: the known fluid density ρ 1 of quality ml/ of the volume liquid that V1=increases of liquid that volume V=beaker 2 increases of tested solid, the quality m/ of the tested solid of density p=m/v=of the tested solid known fluid density ρ 1 of quality m1/ of liquid (increase).
Survey before the density at first and to pour known density and insoluble or indissoluble density into discharge opeing bucket 1 less than the liquid of tested solid, make small amount of liquid flow into beaker 2 from discharge opeing bucket 1, make pilot lamp shinny by " ON/OFF " key 7 opening power then, when liquid is no longer from discharge opeing bucket 1 inflow beaker 2 by the time, by " zeroing " key, display quality and volume all are zero on the display screen at this moment.By " fluid density " key, adjust the fluid density value again with numerical key.At last tested solid is carefully put into discharge opeing bucket 1, liquid just begins slowly to flow into beaker 2, and when liquid was no longer from discharge opeing bucket 1 inflow beaker 2 by the time, shown density value, volume and quality was exactly density value, volume and the quality of tested solid on the display screen.
